Context

“Wherefore it is evident that martyrdom is an act of fortitude; for which reason the Church reads in the office of Martyrs: They "became valiant in battle" [*Heb. 11:34] . Reply Obj. 1: Two things must be considered in the act of fortitude. One is the good wherein the brave man is strengthened, and this is the end of fortitude; the other is the firmness itself, whereby a man does not yield to the contraries that hinder him from achieving that good, and in this consists the essence of fortitude. Now just as civic fortitude strengthens a man's mind in human justice, for the safeguarding of which he braves the danger of death, so gratuitous fortitude strengthens man's soul in the good of Divine justice, which is "through faith in Christ Jesus,"” source
